Fig. z5 4L v Patent@ June 2l, 192k ATTORNE ed by means ot bolts f6, and shims f7, to allow for variation in manufacture and for wear.

At a point below the slack roll f2, on the oscillating frame F, is secured by adjustable pivot fs, a connecting rod d, which is secured to the cross-head l, by pivot'alf.

Four sets of ineens are shown for altering the distance between the pivot f which secures the oscillating traine F to the casing and the pivot f8, j, which secures the connecting rod to the oscillating trarne. the angle of oscillation oiE the trarne F, is always the saine the greater the distance between these two pivots the greater will be the stroke of the piston. ln the Figs. l, 2, 3, 1i, 5, 6, 7, and 8, pivot f8, is eccentrically mounted in the oscillating trarne F, so that by rotating it the distance between pivots f8, and y", `inay he increased or diminished, and is secured against accidental rotation in Figs. l, 2, 3, l and 5 by saw-slots if, bolts im, and seal-plate fu, and seal fm.

ln Figs. 6, 7 and 8 the distance between pivots is also increased or diminished by rotating the pif/ot f8, but a dierent method is shown o securing the eccentric pivot f8, against undesired rotation. Here the pivot carries a lateral extension fla, with holes f, adapted to register with other holes 7m, arranged on an arc in an extension fm, oi the oscillating trarne A pin f, is adapted to pass through any of the holes fm, and j, and he seele-fl in position.

In Figs. 9, l and il the plain pivot which taires the place ot the eccentric pivot fs, is niountec in a slidably adjustable block F1, the adjustment of which increases or diminishes the distance between y and fw.
